Title: Improvements in or relating to means for preventing unauthorised use of automobiles
IPC: B60R25/042
Filed: 1933-02-17
Abstract: 407,517. Preventing unauthorized use. MALLUK, A. M., Hotel Marseilles, Broadway and ALLEN, F. W., Sea Cliff, Long Island, both in New York, U.S.A. Feb. 17, 1933, No. 4990 [Class 7 (ii).] Unauthorized use of automobile engines, or removal of fuel from the tank, is prevented by means controlling (1) a shutter adapted to close the induction pipe, (2) a valve adapted to close the air inlet to the fuel tank, and (3) a locking-device for the screw cap of the fuel tank. A control box 5 mounted on the dashboard contains a cam 20 having slots 19, 42 actuating a pair of levers 16, 39 connected by cables 15, 38 to the shutter 10 and the fuel tank devices respectively. The shutter 10 is pivoted at 11 and acted on by a spring 13 which, when the cable is released, moves the shutter to close the induction pipe 9. The cable 38 pulls a spring-pressed catch 31 from engagement with ratchet teeth on the fueltank cap, and also withdraws a valve, connected to the catch, so as to open the air inlet to the tank and allow fuel to flow to the carburetter. When the automobile is to be parked, a handle on the front of the control box 5 is turned until the indication " parking lock " is visible through an opening in the front of the box, thus turning the cam 20 so that the shutter 10 completely closes the induction pipe, and the catch 31 locks the tank cap, the valve attached thereto also closing the air inlet. When it is desired to drive the car, the handle is turned until the indication " drive release " appears, in which position the shutter 10 is fully opened and the air-inlet valve of the tank is also opened, the tank cap still remaining locked. A further rotation of the handle brings the indication " tank release " into view, and releases the lock from the tank cap also. When the car i.s to be garaged, the handle is turned to " garage lock " position, in which the parts are disposed as shown in Fig. 9, with the shutter 10 partly open but the catch 31 and its valve attachment closed, thus preventing flow of fuel from the carburetter, but allowing use of the fuel remaining in the vacuum tank or pump for handling the car in the garage. The cam 20 is locked in the " parking lock " and " garage lock " positions, by a bolt 49 which is actuated by a key so as to engage a shoulder 51 or a notch 50 in the cam. In a modification, the cam is actuated by electromagnets which are energized by push-buttons fitted in the front of the control box. If the cable 15 is severed, the shutter becomes automatically locked in the closed position by a catch 63, and a similar catch may be provided in connection with the cable 38.

Title: Fluid actuated control system for controlling liquid transferring units
IPC: F15B11/08
Filed: 1964-02-05
Abstract: 1,029,312. Fluid pressure servomotor system. M.DELBERGUE. Feb 5,1964 [Feb 20, 1963],No.4997/64. Heading G3P. Apparatus for controlling the operation of a unit for transferring liquid in dependence on the valve of a parameter associated with liquid contained in vessel comprises a jack 1 which controls the transferring apparatus, such as a pump or valve, the fluid pressure supplied to opposite sides of the jack from a supply 2 being controlled by valves 19,21. When the parameter reaches a predetermined valve, a pressure pulse is supplied through a conduit 7 and flows through a normally open valve 14 to open a valve 15 which permits flow from the conduit 2 through branch 18 and normally open valve 17 to cause valve 19 to open and valve 21 to close whereby the piston 1b of jack 1 moves to the right to start transference of liquid. The pulse pressure in conduit 7 also closes a valve 13 and opens a valve 11 the latter valve thereby operates a whistle 12. With the valve 19 open, a branch 16 receives pressure fluid to open a valve 20 in parallel with valve 15 when the pulse pressure ceases, the valve 13 again opens and pressure in pipe 16 moves the valve 14 to connect the conduit 7 to the valve 17. The valve 15 is also closed when the pulse ceases, but flow through conduit 18 continues through valve 20. When a second pulse is received, the fluid flows through valve 14 to actuate valve 17 which opens the conduit 18 downstream of the valve to exhaust thereby closing valve 19 and opening valve 21 to move the piston 1b to the left. Conduit 16 is also open to exhaust through valve 19 thus closing valve 20. When the pulse ceases, valve 13 again opens and the actuating pressure of value 14 is exhausted to move the valve back to the open position and thus valve 17 to open position.

Title: Improvements in or relating to telecommunication systems
Inventor: KNOX KEITH ANTHONY THOMAS
IPC: H04M9/08
Filed: 1968-02-05
Abstract: 1,261,521. Substation amplifier circuits. POST OFFICE. 5 Feb., 1969 [5 Feb., 1968], No. 5750/68. Headings H4K and H4R. Telephone substation has a receive amplifier 6, Fig. 1, to feed incoming signals to a telephone receiver 7, the gain of which is controlled by the output from an auxiliary microphone 8 arranged to pick up the ambient noise in the vicinity of the substation, the receive amplifier gain being increased as the noise level increases. As shown, send-receive switching is employed controlled by the speech input to microphone 2 and the threshold level at which the station switches from receive to send is also controlled by the output of the auxiliary microphone 8, to increase the threshold level with increase in ambient noise. The auxiliary microphone 8 is arranged to respond mainly to the noise rather than the speech signals while the signal from the normal microphone 2 is filtered at 14 to make the speech detector 15, which operates the send receive gates 4 and 16, more responsive to speech than ambient noise. Detailed circuit of the apparatus is shown in Fig. 2 in which speech signals outgoing from microphone 2, are amplified by transistors TR1 and TR2 and fed via the send gate comprising series resistors R43 and R45 and shunt variable impedances formed by transistors TR13 and TR14, to the send amplifier TR16 which feeds the line. Incoming signals from the line feed via resistor R48 and the receive amplifier TR7 and TR8 to the receiver 7, the receive gate being formed by the transistor TR15 which can be switched to low impedance to shunt the receiver 7. Signals picked up by the auxiliary microphone 8 are amplified by transistors TR3 and TR4 and rectified by transistors TR4 and TR5 to control the impedances of the groups of silicon diodes D1 to D4 and D5 to D8. The group of diodes D1 to D4 forms a shunt impedance on the negative feedback path in the receive amplifier to increase the receive gain as the noise level increases, while the diodes D5 to D8 forms a shunt impedance in an attenuator including the resistors R40 and R42 which feeds the microphone 2 amplifier output to the speech detector circuit including transistors TR9, 10, 11 and 12. With no signal applied to TR9 in the speech detector transistors TR10, 11 and 12 are non-conducting, making transistor TR15 of the receive gate non-conducting so that received signals are fed to the receiver 7. Transistors TR13 and 14 are however made conducting so as to prevent signals being fed to the outgoing amplifier TR16 via resistors R43 and 45. With speech signals at sufficient level applied to transistor TR9 of the detector, transistors TR10, 11 and 12 saturate to reverse the conditions of the send and receive gates to inhibit reception and allow speech transmission.
